The comic is set in a post-apocalyptic future where powerful families vie for control of what is left of the world's resources.

The book focuses on Forever Carlyle, who protects her family as its Lazarus - a powerful warrior who is almost impossible to kill.

"We've been describing it as sort of Godfather meets Children of Men, but that's a little disingenuous," Rucka told Comic Book Resources.

"We've used the phrase 'dystopian future,' but that's a little tired. The idea behind the series is, like they used to say on Max Headroom, 'Twenty Minutes Into the Future' - but it's further than that.

"It's a world that has suffered a huge economic collapse, where the rich and the poor are incredibly divided, where there's very few of the rich and there's lots and lots of the poor. Wealth has become the truest instrument of power, and they'll do almost everything they can to keep it.

"In this world is Forever Carlyle, who is the quote-unquote youngest daughter of the Carlyle family. She is sort of their, I don't want to say secret weapon, but she is the standard bearer for the family's defense.

"As a result of that she's the recipient of everything the family can offer. The Carlyles' wealth and power initially came from the agricultural business and that has lead to genetic modification and that has lead to gene work with people.

"Every family has either a Lazarus or a similar force - it is a title. It is a slang term for this type of person, this individual who is the bloody sword and fire and shield for their family. So that's it, in kind of a nutshell. Forever's story, of course, is that she's not who she thinks she is and it is in many ways a journey of self discovery."
